Weather in August
Temperature
August, marked by an average high-temperature of 31°C (87.8°F) and a low-temperature of 25.1°C (77.2°F), is the warmest month in Tokyo.Heat index
In August, the average heat index is appraised at a very hot 39°C (102.2°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Prevent overexposure. Protection from the sun's harmful effects is needed. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim. Beware! Reflections from sand and water can intensify the Sun's UV radiation.
